# Future Energy Markets: New Opportunities for BESS

> Explore emerging market services and the potential for BESS to unlock new revenue streams as the grid continues to evolve.

BESS assets are long-term investments built for decades of operation. As the energy grid evolves, new problems emerge — and where there are problems, there are also new market opportunities. Being aware of these future markets is crucial for asset owners when forecasting long-term profitability.

## The Evolving Grid: New Problems, New Solutions

The rapid increase in intermittent renewables and the retirement of traditional power plants are creating new, complex challenges for grid stability. Several critical challenges are emerging that BESS assets are uniquely positioned to address.

## 1. The Challenge of "Loss of Inertia"

Traditional fossil fuel power plants contain massive spinning turbines — called **synchronous generators** — that are physically connected to the grid and spin at the grid's frequency (50 Hz). A key property of these spinning turbines is **inertia**: if there is a sudden power event, the heavy turbines do not stop instantly. Their momentum continues to spin for a short while, providing a crucial "reaction time" buffer for grid operators.

Renewable generators like wind turbines and solar panels **do not inherently provide this physical inertia**. They produce electricity electronically. As old fossil fuel plants are retired and replaced with renewables, inertia is gradually being removed from the grid.

This loss of inertia is a significant problem — it reduces the time operators have to respond to sudden power events, making the grid more vulnerable to frequency deviations.

**The opportunity:** As inertia becomes increasingly scarce, **inertia markets** may emerge where TSOs pay assets like BESS to provide a stabilising effect — even if it is "synthetic inertia" rather than the physical spinning mass of a traditional generator.

## 2. Blackstart Capability

**The problem:** In a catastrophic scenario where all power goes out across a large region, generators typically require some electricity input to start up again. If every generator needs an external power source to start, restoring the grid becomes a serious challenge.

**Blackstart capability** is the ability of a power generator or storage unit to start producing electricity without any external grid power input. BESS are naturally suited for this: they store energy and can be designed to self-start and begin energising sections of the grid from scratch.

**The opportunity:** As energy infrastructure becomes more interconnected and the consequences of widespread outages grow more severe, **blackstart markets** could emerge where TSOs pay a significant premium for assets that can provide this ultimate emergency restoration service.

These are just two examples of the many future market opportunities that are developing as the energy transition progresses. They illustrate a broader point: the value of BESS is not static. It adapts and grows with the grid's needs, creating continuous new revenue opportunities for those who are agile and well-informed.

For optimisers in particular, the ability to rapidly identify and access new market opportunities as they emerge is a key differentiator — and a major driver of long-term BESS profitability.
